Localization and Reshaping of Non-Minimum-Phase Zeros in Multi-Converter Systems
Ailixier Yaermaimaiti, Jiaxin Wang, Yunjie Gu +1
Non-minimum-phase (NMP) zeros in multi-converter power systems impose bandwidth ceilings on feedback control, yet quantifying them at the system level has been impractical because…

Power Margin Ratio -- A Large-Signal System Strength Metric for Inverter-Based Resources-Dominated Power Systems
Zitian Qiu, Yunjie Gu
As the growing penetration of inverter-based resources (IBRs) in modern power systems, the system strength is decreasing. Due to the inherent difference in short-circuit capacity c…
